Creighton Model FertilityCare System

The Creighton Model FertilityCare System (CrMS) is named after the University in Omaha (USA) where it was developed in the 1970’s. The goal was to develop a method of capturing the individual nature of a woman’s cycle in a scientifically robust and measurable way.

Women are taught to observe their bodies for biomarkers. Biological markers are in the first instance what the woman can observe on the outside of her body giving insight into internal hormonal events. The menstrual bleed and cervical mucus being the two obvious examples. Women and couples are taught how to record these observations in a coded way.

The result is, that on any given day, couples can know with accuracy whether the day is fertile or infertile. This empowers couples to manage their fertility naturally. It fosters harmony and acceptance of normal healthy body function. They learn that they can manage this reliably. Studies have shown the method-effectiveness as 99.5% and use-effectiveness as 96.8%. The method does not depend on cycles being regular. It can be easily used at times of stress, during breast feeding, peri-menopause etc.

A textbook cycle:

The pattern of the chart that emerges over time shows the uniqueness of each woman, as well as each cycle. Further biomarkers emerge, such as the particular pattern of bleeding, mucus production or the length of different stages of the cycle. These provide women and couples with new dimension on their fertility. They begin to observe how stress particularly, but also diet, exercise etc are being reflected in the FertilityCare record. This adds to a woman’s/couple’s ability to then influence their own gynaecological health and wellbeing through their lifestyle.
